DRAG-SAW.

QJIECIFIGATEON forming part of Letters Patent No. 337,754, dated March 9, 1886.

Application filed April 13, 1885.

To all whom it may concern;

Be it known that I, MADISON M. DRISKELL,

a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Devices for Operating Crosscut-Saws, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in devices for operating crosscut-saws, the object of which is to provide a light, cheap, simple, and durable device for holding and easily driving a crosscut-saw in sawing wood, logs, ice, I 5 870. These objects I attain by means of the device illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a View in elevation of the entire device. Fig. 2 is a top or plan View of the same. Figs. 3 and 4 are detailed views.

Similarletters indicate corresponding parts in all the figures.

A is an ordinary crosscut-saw of any desired size, preferably made to out both ways.

H is a frame, of any desired size, made to support the bearings of the gear-wheels D D and a balance-wheel, C. It is preferably made light, and for this purpose it is composed of posts If h", which have side pieces, h h, and

foot-pieces h if.

C is a heavy balancewheel, which may be attached to the crankshaft d", but is preferably secured to a shaft, 0, which has bearings 5 c 0 and a pinion, D.

D is a cog or drive wheel secured toa crankshaft, d, having bearings d d. Said shaft may be operated by a belt-wheel, but has a crank, E, for turning the same by hand. The crank- 0 handlef has suitable bearings for an arm, F, which connects with the pendent piece G and arm B. The pendent piece G is attached to an upright, 9 in which is a slot, y for abolt, g, which may be moved up or down,as desired,

4 5 and permit the piece G to swing back and forth.

B is an arm for driving the saw. It has a slot, 1), and holes to receive bolts b,for rigidly holding and supporting the saw. The back end of the said arm is supported by bearings on a bolt, f", which also provides bearings for Serial No. 162,167. (No model.)

the arm F and the lower end of the piece G. Said piece G serves to support the elbow'joint formed by the arms F B. The front end of arm B is supported by the saw when sawing, and may be weighted, as desired; but when not sawing or when the saw reaches the de sired depth, it is carried by a wheel, O,which has suitable hearings on a bolt, 0, at or near the front end of the arm. Said wheel is preferably made with a rim, 0, made concave to receive and run upon the upper edge of the track-piece I, which is preferably made rounding or convex.

Track-piece I is secured at one end,i,to a pest,

h, and at the other is suspended by a rope or chain, J, which works over a pulley, K, and

is attached to a lever, L, by which the front end of the track-piece is raised or lowered, as desired, thus raising or lowering the saw. The back end, i, of the said track-piece is bent or preferably made wider, as shown, so as to always carry the saw on a level in moving back and forth when supported by the arm.

L is a lever having an edge made 'and bent so as to catch in notches m of the quadrant or semicircle M.

m is a pin or bolt placed in one of the holes m so as to stop the saw from dropping below a point desired, or so that the saw will be supported by the track-wheel when the stick of wood, &c., is sawed off.

S is a device for attaching the lever L so as to automatically throw the lever and hold it in the notches. It is composed of a plate, S", having a central hole, S, and springs S attached beneath the lower side, so as to raise the lower side, S and press the upper side,

S against the outside of the lever above the pivot-bolt,and thus force it into the notches m.

P is a saw-buck having a piece, 1), to serve 9 as a guide to form with the leg 1) a slot, 12", to keep the saw in position. It also has a piece,

for securing the sawbuck to the frame.

The deviceis operated thus: In sawing stovewood, 810., the saw-buck is attached, as shown. The lever L is drawn back and caught in one of the notches m, and thereby raises the saw until the wood is placed to be sawed. The lever is then placed back against the bolt m".

The operator,taking hold of the handlef,turns roo the crank in either direction, as desired. This turns the drive-wheel D, which turns the pinion D and sets the balance-wheel O in rapid motion. This great velocity of the balancewheel assists in driving'the saw, so that the wood, &c., is easily and quickly sawed off. The lever is again raised to put the stick up in place for being sawed.

This device is of great use in sawing logs. In this case the foot-piece h is placed against the side of the log, and dogs Q are attached to the frame, preferably at points 9 q,to firmly attach the dogs or hooks Q, for securing the log to the frame. It is then operated as in sawing wood, &c. This saw is very convenient, as the device causes the arm and saw to pass at the operators side, so that it is not necessary to walk to place and regulate the wood, &c., while sawing, as the saw-buck is brought so close to the operator.

Having thus described the construction, use, and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A sawing device composed of a drag-saw supported by an arm, B, said arm being pivoted to a supporting-piece, G, and a drivingarm, F, and provided with a wheel, 0, which runs upon a track-piece, I, which is pivoted to a frame, as is also the sup porting-piece G, said frame supporting a shaft provided with a balance-wheel, cog-wheel, pinion,and'a. winch for driving the saw, on which the arm F has bearings, and a chain, J, attached to the trackpiece'a'nd to a lever provided with a quadrant, all substantially as set forth.

2. The combination, with the main frame H, to which is pivoted a lever, L, connected by a chain,,J, to one end of the track I,which is pivoted at the other end to the main frame, of a plate, S attached near the lower end of said lever by a bolt passing through a hole,S, in the center of said plate, and springs S, attached near its lower side, S, substantially as and for the purpose set forth.

In testimony whereof I aflixmy signature in presence of two witnesses.

MADISON M. DRISKELL.
